XSLT

I writed template that return maxNumer.

<xsl:template name="selectMaxNumber">
  <xsl:param name="numbers" />

  <xsl:for-each select="$numbers">
    <xsl:sort data-type="number" order="descending" />
    <xsl:if test="position() = 1"><xsl:value-of select="."/></xsl:if>
  </xsl:for-each>
</xsl:template>

But I can not call this template/ I can not send parameter as numbers list.

For example, the next code return error

     <xsl:call-template name="selectMaxNumber">
        <xsl:with-param name="numbers" select="$rootFolder/node/@nodeName" />
      </xsl:call-template>

The node names is years so it is number.

Hi AlexR,

Parameter "numbers" you're passing to your template is passed as a string, so you could use number($rootFolder/node/@nodeName) to get around that. But, even if you'd pass this to your template, I still can't figure out what you're trying to do with it.. you're passing a single number and using a for-each to iterate... I don't see the relation here...

Could you elaborate on your content structure so we get a visual clue on what you're trying to achieve.

Cheers,

/Dirk

Hi Dirk,

I want to pass list of years to selectMaxNumber template.

For example if I have next xml
```
<node nodeName="newsFolder">
  <node nodeName="2009">
    ...
  </node>
  <node nodeName="2010">
    ...
  </node>
</node>
```
I want to pass numbers "2009 2010" as list to parameter numbers.

And I want get 2010 as result of selectMaxNumber template.

The xpath expression "$rootFolder/node" pass correct nodes to template. But it pass nodes, not nodeNames.

I thinked that xpath expression "$rootFolder/node/@nodeName" will pass list of nodeNames (2009 2010), but it pass only first nodeName.

Why xpath expression "$rootFolder/node" pass list of nodes, but xpath expression "$rootFolder/node/@nodeName" pass only fist nodeName?

For example

xpath "$rootFolder/node[1]/@nodeName" return first nodeName.

xpath "$rootFolder/node[2]/@nodeName" return second nodeName.

so "$rootFolder/node/@nodeName" should return all nodeNames. But it doesn't.

I want pass list of nodeNames to template. How can I make it?

I know that I can rewrite selectMaxNumber template to select nodeName inside it. But I want to write universal template to select max number.
